Description
The Honeywell RP670B1009 is a Double-Pole, Double-Throw (DPDT) pneumatic switching relay designed for HVAC applications where control sequences change based on pilot pressure variations. It facilitates the switching, blocking, diverting, or bleeding of pneumatic air lines when pilot pressure shifts between specific values, such as 3 and 7 psi. This relay is commonly utilized in systems with multiple operating conditions, including Day-Night, Summer-Winter, Start-Stop, and On-Off-Auto sequences.
